iMPROVEMENT IN FARE-REGISTERS.

Specification forming part of Letters Patent No. 207,740, datedSeptembcril, 1578; application tiled August 8, 1878.

To all 107mm it may concern:

Be it known that I, WILLIAM H. HORNUM, of the city, county, and State ofNew York, have invented a new and useful Improvement in Fare-Registers,which improvement is fully set forth in the following specification,reference being had to the accompanying drawing, in which- Figure 1represents a section in the plane 90 1, Fig. at. Fig. 2 is a face view.Fig. 3 is a section in the plane y y, Fig. 4. Fig. 4 is a transversesection in the plane 2 2, Fig. 1.

Similar letters indicate corresponding parts.

This invention consists, first, in the combination, in a fare-register,of a trip-registering disk operated step by step by a prime mover, anindependently-pivoted rotating disk con centric therewith, and adaptedto be turned forward by hand, mechanism for engaging the two disks whengiven points thereon coincide, a safety-pawl for preventing theregisteringdisk from moving forward more that one step at a time, andmechanism for disengaging said safetypawl from said wheel andsimultaneously locking the prime mover of said wheel, substantially ashereinafter described; second, in the combination, in a fare-register,of a trip-registering wheel operated step by step by a prime mover, arotating disk adapted to be turned forward by hand, mechanism forlocking said rotating disk at a given point and simultaneously releasingthe registeringdisk from a zero-guard, substantially as hereinafterdescribed 5 third, in the combination, in a fare-register, of astep-by-step registeringwheel operated by a prime mover, a safetypawlwhich prevents said wheel from turning,- a rotating plate pivotedconcentrically with said registering-wheel and adapted for engagementtherewith at a single point, said rotating disk being adapted to beturned forward by hand, mechanism for locking said rotatin g disk andfor unlocking the same, and simultaneously and automatically locking theprime mover, and operating a zero-guard to prevent the movement oftheregisterin g-wheel beyond a certain point, substantially ashereinafter described.

In the drawing, the letter A designates a case which inclosesthercgistering devices and the mechanism for actuating the same.

In the example shown in the drawing I have represented only the unitdiskB of the tripregister but in practice said trip-registerconsists of aunits-disk and tens-disk, which work one insideihe other. Thepermanentor general register is also omitted in the drawing, since the same formsno part of my present inven t-ion.

The units-diskB is firmly secured to aratchet wheel, a, and bothtogether turn freely on astud, b, fastened in the partition-plate of thecase A. The forward motion of the units-disk or of the trip-rcgisterisproduced by the action of a slide or prime mover, C, (see Fig. 3,) whichcarries a sprin g-pawl, c, that acts against the square shoulders of theteethof the ratchetwheel a whenever said prime mover is drawn out. Astop-pawl, d, prevents the trip-rcgis ter from being rotated in thewrong direction. lVith the ratchet-wheel a is combined a safetypawl, e,which engages with notches f in the edge of said wheel. lVhen theprime-mover is drawn out a sprin g-pawl g,secured to said prime mover,strikes the tail of the safety-pawl c and throws said pawl out of gearwith the ratchetwheel just before the actuating-pawl 0 begins to act;but as soon as the spring-pawl g has passed the tail of the safety-pawlc the latter bears down upon the inclined face of the tooth of theratchet-wheel just opposite to it, and as soon as the ratchet-wheel hasbeen rotated for the space of one tooth the safety-pawl engages with thenext notch f, and thereby the tripregister is prevented from movingforward more than one number for each stroke of the prime mover.

ith the trip-register is combined a plate or disk, D, which may be ofthe same diameter, or nearly so, as the registering disk or disks of thetrip-register, and provided with an aperture, h, through which thefigures of the trip-register can be seen, or which may be madeconsiderable smaller than the registering disk or disks, so that it doesnot cover up the figures on the same. This plate turns freely on the hubof the units-disk, and it is provided with a finger-button, i, by meansof which it can be turned forward, a pawl, j, which engages withratchet-teeth 7a in the edge of said plate, preventing its backwardmovement. ()n the inner surface of the plate D is a spring-pawl, Z, andwhen the plate is turned forward this pawl strikes a pin, m, whichprojects from the face of the units-disk,

' so that said units-disk is compelled to turn 1/ /also. Whenever thepawl l strikes the pin m the aperture h in the plate D is over thecipher on the unitsdisk, and by turning the plate D forward thetrip-register can be set to zero. WVith the plate D is combined astop-lever, n, which engages with a notch, 0, (see Fig. 1,) and whichalso carries the zero-guard 1), both these parts being made to turn onacommon fulcrum, q. From the lever 02 projects a fingerpiece, 1", througha slot, 8, in the face-plate of the case A. hen the stop-lever n isthrown in gear with the notch 0, the plate D is locked and preventedfrom being displaced accidentally. At the same time the zero-guard p israised, so that it does not obstruct the motion of the trip-register;but when the stoplever is thrown back out of gear with the notch 0 thezero-guard p is moved in the path of a pin, t, secured in the units-diskB, and the forward motion of the plate D and of the trip-register isarrested at zero, the aperture h of the plate D being opposite a glazedopening, a, in the front plate of the case A, and the cipher or ciphersof the trip-register being exposed to view. With the stop-lever n isalso combined a latch, '0, which is adapted to engage with a notch, 20,Fig. 3, in the prime mover, so that whenever the stop-lever is thrownout of gear with the notch 0 the prime mover is locked, and thetrip-register can be moved forward only by the action of the plate D.lVhen the stop-lever n is thrown back it or any part connected theretoacts on the safety-pawl e, so as to throw the same out or gear with theratchet-wheel a and allow the trip-register to turn forward with theplate D.

By the action of the safety-pawl the registering-disks are preventedfrom being propelled forward by the action of the prime mover more tl none number at a time, the zeroguard pl vents the registering-disks frombein g flung around independent of the plate D, the latter beingarrested by hand, and the latch 11 prevents the conductor from ringingthe alarm during the time the trip-register is free to be set by hand;and when the rotating plate is made to cover all the figures but one onthe disks of the trip-register the stoplever prevents said plate fromgetting accidentally displaced, so as to conceal all the figures of thetrip-register.

The rotating plate, when tlmsconstructed, I do not claim as myinvention, such ihavin g been used before.

What I claim as new, and desire to secure r by Letters Patent, is- V 1.The combination, in a fareregister, of trip-registering disk operatedstep by step by a prime mover, an independently-rotatin g diskconcentric therewith and adapted to be turn ed forward by hand mechanismfor engaging the two disks when given points thereon coincide, asafety-pawl for preventing the registeringdisk from moving forward morethat one step at a time, and mechanism for disengaging said safety-pawlfrom said wheel and simultane ously locking the prime mover of saidwheel,

substantially as described.

2. The combination, in a tare-register, of a trip-registering wheeloperated step by step by a prime mover, a rotating disk adapted to beturned forward by hand mechanism for locking said rotating disk at agiven point and simultaneously releasing the registeringdisk from azero-guard, substantially as de scribed.

3. The combination, in a fare-register, of a step-by-stepregistering-wheel operated by a prime mover, a safety-pawl, whichprevents said wheel from turning, a rotating plate pivotedconcentrically with said registerin g-wheel and adapted for engagementtherewith at a single point, said registering disk being adapted to beturned forward by hand mechanism for locking said rotating disk and forunlocking the same and simultaneously and automatically locking theprime mover, and operating a zero-guard to prevent the movement of theregistering-wheel beyond a certain point, substantially as described.

4. The combination, with the registeringwheel having pin t and itsratchet-disk a, of the safety-pawl e, prime mover O, trip-pawl g,stop-lever a, latch c, and zero-guard 19, substantially as described.

In testimony that I claim the foregoing I hereunto set my hand and sealthis 30th day of July, 1878.

WILLIAM H. HORNUM.
